WINDOW.- LOCKING ARRANGEMENT.

Application filed May 8,

To all whom it may concern:

'Be it known that I, JosEPH PERZESZTY, a citizen of the United States, residing at New York, inthe county of New York and State of New York, have invented certain new and useful Improvements inWVindow-Locking Arrangements, of which the. following is a specification. v

This invention relates to windows, having more particular reference to a window ar ranged to open both by a vertical sliding movement of the sashes and also by a horizontal swinging movement.

The invention has for an object to provide a novel and simple window construction as above set forth which permits of a partial opening of the window by sliding one or both of the sashes, or a complete opening thereof by moving the swinging elements.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a perspective view showing one embodiment of my improved window.

Fig. 2 is a face view thereof.

Fig. 3 is an enlarged fragmentary hori zontal section on the line 33 of Fig.2.

Fig. 4 is a face View showing the invention applied to a different form of window.

Referring now to Fig. 1 of the drawings an ordinary window frame is indicated at 10. I11 this frame are slidably supported, in the usual manner, an upper sash 11 and a lower sash 12, the sash cords being omitted fro-m the drawing.

Instead of fixing the panes, indicated at 13 and 14, directly to the upper and lower sashes as is customary, they are fixed in supplementary sashes 16,17 suitably fitted into the sashes 11 and 12 respectively. These frames are shown in Fig. 1 as hinged at one side as at 19 to the sashes 20 and provided with novel locking means to be presently described.

As will be apparent, either of the sashes 11, 12 may be raised or lowered as desired, while the full window area may be utilized for ventilating by opening the supplementary sashes 16, 17.

My improved locking means is of a uni- 1922. Serial No. 559,136.

tary nature whereby both main and supple mentary sashes are lockedby the one device. As here shown a pair of fingers 25, 25 are fixed on stub shafts 26 and 26 journaled in bracket elements 27 on top of the lower sash 12. These fingers extend respectively upward and downward along the faces of the sashes 11 and 12 and have laterally projected upper and lower ends 28 and 29' adapted to engage the free edgesof the sup plementary sashes 16.and 17.

The shafts 26, 26' have fixed thereto bevel gears 30, 30 engaged by a single bevel gear 31 fixed on one end of a shaft 32 extending along the top edge of the lower sash 12 and having another bevel gear 33 on its other end. This latter gear 33 meshes with a bevel gear 34 loose'on a bolt 35 adapted to engage in a socket 36 in the upper sash 11, the gear 34 being held against axial movement between a pair of bracket elements 37 fixed to sash 12 and in which the bolt is guided, the bolt being held against rotation by a stud 38 on one of the elements 37 projecting into a longitudinal groove 39 in the bolt.

Formed in the bolt 35 is a spiral groove 40 in which engages a stud 41 fixed in the gear 34, so that sliding movement of the bolt imparts rotative movement to the gear 34. The bolt is operated in a locking direction by means of a cam 42 pivoted as at 43 on a support 44 on the lower sash 12 and, having an integral operating arm 45, retraction of the bolt 35 being effected by an expansion spring 46 coiled therearound.

As will be readily understood, when the arm is swung to push the bolt 35 into the socket 36, and so look the two sashes 11, 12 against sliding movement, the finger ends 28, 29 will be likewise swung to project across the supplementary sashes 16 and 17 and so look the latter closed.

A further advantage of my improved window, in addition to that set forth above, is that it facilitates washing thereof since the outer faces of the window panes are rendered easily accessible.

In Fig. 4 I have shown the invention applied to a window comprising the frame 10 and sliding sashes 11 and 12. In this figure however, the supplementary sashes, indicated at 16 and 17 instead of being hinged at the sides as in Figs. 1 and 2, are pivoted as at 23 midway between their side edges.

Having thus described my invention what 2 I claim as new and desire to protect by Letters Patent-of the United States is as follows:

1. A window comprising upper and lower a sliding sashes, and supplementary pane carrying sashes each movably mounted in said sliding sashes and enclosed on all sides by the latter, and a unitary means for looking l of said sashes.

2. A window comprising upper and lower sliding sashes, and supplementary pane carrying sashes hinged to said sliding sashes and enclosed on all sides by the latter, and a common locking mechanism for all of said sashes.

3. In a window, upper and lower sliding sashes, supplementary pane carrying sashes hinged thereto, pivoted fingers adapted to engage and look said supplementary pane carrying sashes to the said sliding sashes, a bolt adapted to lock said sliding sashes together, and means whereby operation of said bolt causes operation of said fingers.

4. Ina window, upper and lower sliding sashes, supplementary pane carrying sashes hinged thereto, pivoted fingers adapted to engage and lock said supplementary pane carrying sashes to the said sliding sashes, a bolt adapted to lock said sliding sashes together, and means whereby operation of said bolt causes operation of said fingers, said means including a bevel gear loose on said bolt and carrying a stud projecting into a spiral groove in said bolt.

In testimony whereof I have afiixed my signature.

JOSEPH PERZESZTY.
